GAS-HEATER FOR AUTOMOBILES.

' v Application filed January 17, 1919. Serial No. 271,657.

To all whom it may concern Be it known that l, CHARLEY Mormon STUDEBAKER, a citizen of the United States. and a. resident of Centropolis, county of Franklin, and State of Hand 1 ive invent ed certain new and useful m. ovoinents in Gas-Heaters for Automobile, of which the following is a specification.

My present invention relates generally to gas heaters, and more particularly to an attachment for automobiles to assist in starting in cold weather, n1y. object being the provision of a simple, inexpensive arrangement which may :be quickly applied, and which may "be utilized without inconvenience and Will effectively and eiliciently open ate for the intended purposes.

More particularly my invention relates to that. type of heater in which a casing is secured to surround a portion of the intake manifold of a combustion engine, having provision for'the ready introduction of comloustible matter as well as provision for the introduction of the heat units and products of combustion-thereof into the air intake pipe of th carburetor, so to actually introduce preheated gases within the combus- 'tible mixture for the motor as Well as heat the intake manifold through which the com- 2 c bustible mixture passes from the carburetor to the motor.

In the accompanying drawings illustra ing my invention and forming a part of this specification:

Figure l is a perspective view illustratingv the practical application of my invention;

Fig. 2 is a similar view on a slightly onlarged scale, with the cover of ,the heater casing removed and in detached relation; Fig. 3 is adetail perspective View of the pad holder;

Fig. i is a vcrticalsection through the air intake pipe and taken substantially on line d-d: of Fig. 1.

Referring now to these figures, my invention resides in the provision of a casing generally indicated at 10, in connection with the intake manifold 11 of an internal combustion motor, this casing having its base 12 apertured to receive the vertically extending portion of the manifold and provided with" side walls 13 inclined upwardly and out.

wardly from the sides of the base 12 with their upper ends concavely recessed at 14 toreceive the lateral portions of the manifold. A back plate 15 is connected to the rear edges of the sides 13 and has its upper portion 16 curved to partially surround the manifold so as to cooperate with the upper curved portion 17 of the front wall or cover 18, the upper curved portion 17 of which partially surrounds the opposit side of the manifold clearly seen in F igj 1. This front wall or cover plate engages the front edgesof therbase 1-2 and sides-13 and is secured in its operative position to the casingv 'by means of bolts and nuts 19 as seen in Fig 1. no side wall 13 has an opening communicating with the upper end of a depending box-like extension 20 of the casing, the upper end of wh1ch1s secured to the casing around the said opening of its Side wall,

and one side of which-has an opening 21 normally closed by a hinged cover 22. This extension 20 of the casing also has a hinged base plate normally closing its lower- 'door or cover in the open position. shown in Fig. 1, so that -11p0n igniting said combustible material the heat of its combustion will be transmitted directly to the intake manifold with which it is in contact.

At the same time the casing cover 18 has an opening communicating with one end of a heating pipe 27, which is preferably of a flexible nature, having a valve 28 therein at a convenient point in its length and having its opposite end secured to surround an opening in the air intake pipe 29 of the can buretcr 30, which carburcter also connects with the intake manifold as usual. In thus connecting the pipe 27 with the air intake pipe, the respective end of the pipe 27 has an annular series of longitudinal slits forming tongues 31 as seen in Fig. 4, certain of which, for instancealternatc tongues, are bent outwardly to bear upon the external surface of pipe 29, and the others of which are permitted to extend inwardly of the Patented.

opening of the pipe. A clamp 32 surrounding, the pipe 52$) and-withportions thereof overlying the outwardly bent tongues oft-lie pipe 27 thus securely fastens the two pipes together i In operatlon, when it is'desired to start the motor in a cold state, the combustible fluidis introduced as above described and as lllllS- trated in Fig, l, and the intake manifold be comes promptly warmed 'so as to preheat the combustible mixture on its way to the eyiit is obvious that my invention provides a device of this nature which may he quickly installed, and which may be utilized conveniently and effectively, and which will. he

.i durable in operation.

I claim: v 1. The'combination with the earbureter, and the air pipe and intake manifold to which the -carbureter is connected, oi a casing secured to surround a portion of the intake manifold, having pad holdingmeans therein and provided with a hii'iged door, and a pipe connected at one end to the said casing and at its opposite end to the said air pipe of the carbureter and having a valve. for the purpose described,

The combination with the intake manifold, carburetor, and carburetor airpipe of a n'i0t0'r, said air pipe having an opening" adjacent the carburetor, of a pipe one end of which is clamped to the said air pipe to register with the opening thereof, a val vo Within the last mentioned pipe and a heater surmounting a portion of the intake mani foid, and to which the opposite end of the I last mentioned pipe has a communicating connection,

3. The combination with the intake manifold of a motor, of a casing having an apertured base to receive throhgh its aperture one leg of the manifold and provided with sidewalls, the upper ends 01 which are coneavely recessed to receive the other lee of themanifold, said easing including a rear *all the upper and of which is curved to partially surround the intake manifold at one side, a cover plate secured to normally cover the opposite side of the casin g and having its upper portion curved to partially surround the opposite side of the manifold, said casing;- having an extension at one side opening into the same and provided with a normally closed door to permit of ready aeoess to the interior of the casing for the purpose described.

at. The combinationwith the intake manifold of a carburetor and :1 carburetor air pipe-of a motor, said air pipe having an opening therein adjacent to the carburetor, of 'a pipe having a valve and provided with an annular series of longitudinal slits at one end forming an annular series of tonguescertain of which are extended into the air pipe opening and certain of which are bent outwardly to engage the external surface of th air pipe, a clamp surrounding the air pipe and having portions thereof overlying the out ardly bent .tongues to secure the last mentioned plate upon the air pipe, and a heater surmounting' a portion of the intake manifoldand with which the opposite end of the last mentioned pipe cmnmunicates for the purpose described.
